That's not true, deno compiles TypeScript to JavaScript, it just does it transparently. The code still runs on v8.
V8 also doesn't run js, it does some byte code compilation stuff amongst other things, then interprets that. But that's all a bit pedantic too, V8 runs js, deno runs ts.
fwiw https://deno.com even has as one of their first bullet points that they have "native support for TypeScript and JSX"
Sure, but part of the claim was "without any compilation". But bun/deno do compile TS into JS.
